Nainggolan has been heavily linked with a move to Chelsea.

Former USA defender JanuszMichallik believes that Manchester United will complete the signing of Roma midfielder RadjaNainggolan as he is someone who would seamlessly fit into the United midfield and work brilliantly alongside Paul Pogba.

The Red Devils have been in the market for a midfielder this summer, with Jose Mourinho also linked with a move for Monaco stalwart Fabinho to shore up the centre of the field and allow Pogba to make runs into the opposition box. Nainggolan has scored 11 goals in 35 Serie A appearances for Roma in the recently concluded season. He has more than three years left to run on his contract at the StadioOlimpico.

"That's a hit for anybody," Michallik said on ESPN FC when asked about Nainggolan's future, as quoted by the Express, "I can understand why Jose Mourinho's been after him for a long, long time now. I don't know if it's going to happen, it's a funny one.

"He's very much like Vidal, you and I joke that if Jose Mourinho had a chance to get (Arturo) Vidal, Nainggolan and (N'Golo) Kante, that would be the midfield and he would make that midfield happen somehow.

"I think that should be a priority over anything there, I think he would help Paul Pogba tremendously as well. So for me this is a hit and it should happen and I somehow think it will happen."
